Hi, I recently got a prada black nylon messenger bag and used it for a trip to London. We went by coach so my bag was allover the place, on the floor, on the shelves and it even got coke allover it. Then I just wiped it down and it looked amazing again . When I had my LV keepall, I put it on the floor in the airport and it gets dirty the dirt didnt come off. PRADA is a god send and I will be getting more nylons...there the best thing ever and will last a life time. Ive never had so much compliments over a bag...even not LV.
